Portrait of Madame Laura Leroux Jean-Jacques Henner (1829-1905)

The picture has something of this: people, wear, portrait, woman, veil, outerwear, man, retro, fashion, coat, gown, model, lid, outfit, cape.
Perhaps it’s a painting of a woman in a black dress with a large hat on her head and a black cape over her shoulders, standing in front of a blue background.
